This document discusses Maslow's hierarchy of needs theory and ERG theory of motivation. Maslow's hierarchy categorizes needs into existence needs, relatedness needs, and growth needs. Existence needs are basic needs like food and shelter. Relatedness needs are needs for relationships and belonging. Growth needs are needs for self-development. ERG theory classifies motivators into existence, relatedness, and growth outcomes. Existence outcomes relate to physical conditions like pay and security. Relatedness outcomes involve relationships and belonging. Growth outcomes concern challenging work, responsibility, and achievement. The document also discusses need for achievement, affiliation, and power as individual motivators.
